The compound interest formula is given by:

Where A is the amount of money, P is the principal(the initial sum of money), r is the interest rate(as a decimal value), n is the number of times that interest is compounded per unit t and t is the time the money is invested or borrowed for.

In this exercise, we have:

.

We want to know the CD's worth in 14 years. So .

So

The CD will be worth $1810.44 in 14 years.

y = x + 95

y = 42 + 95
